Referring to the drawings, a device is shown in Fig. 5. chain 13 being engaged over showncomprising a pair of curved arms 10 hook'll 'to hold the tension. A short lengt having circular end portionshingedly conof wire 15 is then twisted about the wire l i fnected' in overlapped relation by the pivot at one side of the device, shown inFig. rivet 9. The arms 10 as shown in Fig. 1 nor- 5, and the other end of this wire isthen mally' diverge from each other and the same ried across the device and twisted about the are provided at thesame'side of the device wire 14 at the other side of the device as with'projections 10. These projections have shown in Fig. 6. This wire canbe read ly 7 of pliers such as shown-at '16 in Figs. 5 and 6. When the "wire 15 is twisted about the wire :14 at both sides of thedevice; the'han'dle. of
